Reserve Bank of India Governor Raghuram Rajan has said India cannot expect to accelerate its economic growth to 9% per annum unless it improves its supply chain, to prepare to the increase in demand that a higher growth rate could lead to.He added that besides supply of goods and services, India must also improve the quality of its human capital and, which will need steady progress rather than an overnight elimination of constraints.RBI Governor added the current government's Make in India slogan will work better, if it just creates an enabling environment like easier tax structures and allow companies to select what they want to do.He said India chose to support small industries to create jobs which was decimated by global competition, but it would have been better if we had supported large industries because it would support a large amount of jobs.RBI Governor Raghuram Rajan was speaking at a seminar organised in Mumbai today by 'Gateway House', a private think-tank on foreign policy.
